HOLE STRUCTURE FOR EMBEDDING ANCHORS AND GROOVE FORMING DEVICE
To provide a hole structure that can resolve filling defects for holes for embedding anchors that are drilled horizontally, and a device that can realize the structure.SOLUTION: The present invention is provided with a guide part that limits the movement of a rod 20 so that a drill blade 30 of a drill part contacts only the lower half section of a hole, and a groove Z is formed only at the lower half section of the hole inner peripheral surface. A filling material easily flows into the groove Z that is formed only at the lower half section of the hole, and this prevents filling defects for the filling material.SELECTED DRAWING: Figure 3
【課題】水平方向に削孔したアンカー埋め込み用の孔において、充填不良の懸念を解消可能な孔構造ならびに当該構造を実現可能な装置を提供する。【解決手段】ドリル部のブレード３０を孔の下半部にのみ接触するようにロッド２０の移動を規制する案内部を設けて、孔の内周面の下半部にのみ溝部Ｚを形成する。孔の下半部にのみ形成した溝部Ｚは充填材が流れ込みやすいため、充填材の充填不良が発生しにくい。【選択図】図３
